GDA Technologies Ships Configurable USB 3.0 Controller

Innovative USB 3.0 technology enables higher performance, is adaptable across numerous functions

SAN JOSE, Calif., Nov. 18 /PRNewswire/ -- SuperSpeed USB Developers Conference -- GDA Technologies, Inc., a leader in high-speed serial connects, announced plans today to ship "Pravega" - its USB 3.0 family of cores consisting of a highly configurable SuperSpeed device and host controllers that are interoperable with third-party USB 3.0 PHY's running at 5 Gbits/s maximum speeds.

The first product in the Pravega family to be made available to customers will be a Device Controller Core. It can be configured to support any allowed number of Bulk, Isochronous, and Interrupt endpoints. Control endpoints can be supported natively by the core or optionally by an external processor.

The Pravega Device Controller core is architected with a high-performance DMA engine and application interface for maximizing performance of streaming data and can be easily adapted to support host functionality. Optionally, the core can also be configured to operate with a customer's existing DMA Engine.

"Our highly configurable USB 3.0 controller cores are architected for easy integration across a variety of applications that are enabled by Superspeed USB specifications," noted Ravi Thummarukudy, VP and General Manager of IC and IP division at GDA, in a statement. "Applications with video downloads can see download times decrease from about an hour down to 20 seconds with USB 3.0. While providing these SuperSpeed capabilities, of course, we will maintain compatibility with the existing USB 2.0," Thummarukudy added.

The Pravega Device Controller core supports all defined USB 3.0 power states, with the design carefully partitioned to support standard power management schemes. Optionally, it can be configured to manage power mode transitions of the controller and USB 3.0 PHY the enable the aggressive power savings required for mobile and handheld devices.

The controller itself features a very simple application interface that can be easily adapted to standard on-chip-bus interfaces such as AXI, AHB, and OCP as well as other standard off-chip interconnects.

The controller's simple, configurable, and layered architecture is independent of application logic, PHY designs, implementation tools and, most importantly, the target technology. The GDA solution allows licensees to easily migrate among FPGA, Gate array, and Standard cell technologies (ASICs) optimally. Its flexible backend interface makes it especially easy to integrate the solution into a wide range of consumer applications.
